A particle (m = 20 mg, q = -5.0 mC) moves in a uniform electric field of 60 N/C in the positive x direction. At t = 0, the particle is moving 30 m/s in the positive x direction and is passing through the origin. Determine the maximum distance beyond x = 0 the particle travels in the positive x direction.
a. 25 m
b. 20 m
c. 15 m
d. 30 m
e. 60 m

Question 2

A particle (m = 20 mg, q = -5.0 mC) moves in a uniform electric field of 60 N/C in the positive x direction. At t = 0, the particle is moving 25 m/s in the positive x direction and is passing through the origin. How far is the particle from the origin at t = 2.0 s?
a. 80 m
b. 20 m
c. 58 m
d. 10 m
e. 30 m
